Other that those for the encoder, the header I/O pins are not labeled. There's not enough pico acres on the PCB to do a good silk screen. Use a continuity tester from the Mega pin to a header pin to find out how they are mapped.

Having successfully completed the build according to instructions I'm now looking for a Pin numbering of the outside headers as well as
wireup instructions for connecting to BitX board as i'm not sure what the connection marked SQR is intended for and do i use Out2 or Out for the BitX ?
and which additional peripherals are needed for the keyer function besides 3 pushbuttons, stereo Jack for the paddles , Speaker? and where to connect those.
did i somehow miss this or was it not posted yet?

Re: W8TEE TFT/ VFO DISPLAY BOARD BOARD
Usually, failure is because the clock and data lines are not connected to the proper I/O lines on the controller. What type of encoder are you using?

Hi Charlie;
did you change the Bandend to 7200 for Europe? If you did so, you have also change line 1417.

How much current draws the entire board in operation?
My board takes ~300mA at 12,6V and I see a little brightness flicker on every operation on the display.
Is this normal?
The Testpoints voltage are OK.

D18 is ok ! about 12V on both sides ( Diff 0.6V )
but it looks like I was to sleepy when tested Voltage on LM386 yesterday evening
pin 1 : ? ? ? ? ? ? ?1.37 V
PIN : 2, 3 and 4 0 V
Pin 5: ? ? ? ? ? ? ?4,7 V
Pin 6 : ? ? ? ? ? 10,8V
Pin 7 : ? ? ? ? ? ?5,6 V
Pin 8 : ? ? ? ? ? ?1.34 V

perhaps one needs to replace with 1 amp diode? - preferably one like 1N5819 and manage to park it on the smd board

What power voltage are you using?? The BITX does not like more than 13.4V.

There isn't, at
least not for the BITX40.

I think at that price I might as well order the
entire kit and have a spare raduino for $14. There's probably a
reason they don't advertise this option, like it's a loss
leader.?
On a side note - and this may make me a sadist - I wonder
if there's an option to order a completely unassembled kit.
Imagine the challenge (agony) of soldering your own SMTs, and
the bragging rights if it work!

Ik weet niet veel over problemen met het schieten van de bitx, maar ik heb ontdekt dat google een geweldige taal vertaler heeft. Het was gewoon een kopie en pasta en altviool, de tekst in het Engels. Ik hoop dat de oplossing voor de metronoom een ??makkelijke is. 73's RCC

Thanks! DuWayne good stuff.
Anyone that wanted a board like the red one posted above I did reorder more and will again offer at cost. The last price was best guess from just an envelope and a stamp so pending no crazy stuff at the Post Office price will remain the same. Please keep in mind I am not a store so hold all requests until the new batch is posted. They will be like the red ones above and not the updated silk like DuWayne posted.
?Should be about 2 weeks

I did this board layout after the AGC mod first came out. ?They were just for me, so I did not bother with parts layout.
Seeing the interest after David offered up his extra boards, I updated the files and added a parts layout PDF to the dropbox files at
https://www.dropbox.com/sh/pg3otf9cwtekkoo/AADGvAfmP_E96njuNP5UX_Y9a?dl=0
I also uploaded this as a shared project at OSHPark.com . ?Boards can be ordered from them, and I know they will ship to DX.
Their price is about $12 for 3 boards including shipping to the US. ?Don't have any idea what shipping to a DX location would be.
The link is ?

Re: Re[Bitx20] Spare Raduino Boards and PCBs
I also have a Complete Raduino Board I designed.? It has lots of
features better than original.
RaduinoX
*I2C connector for controlling more I2C, like another SI5350 or
I2C LCD.
*Spare I/O pins brought out.? D0 and D1 too!
*Rotary Encoder Connector with Pull-ups and De-Bounce Caps, makes
it a lot easier to go Rotary.
*Much better PS conditioning.
*Nano mounts in Sockets and on Back for easy removal.
*USB faces to edge of box side.
*Contrast Pot accessible.
*All Arduino outputs brought out to connectors.
*Level Shift? for SI part to operate per
specification.
*Completely compatible to Original Raduino .? Fits LCD perfectly.
Here is a Picture of RaduinoX.
Bare PCBs are $9, shipping included.
I will ship them to US (48 St.) USPO with Nano $38 without $34.?
I have been bit on Paypal charges, so $2 for paypal.
I have several built and tested.? Privite email me if you are
interested.? "MotDog at Verizon dot net".
Bare PCBs are $9, shipping included.

I am surprised that one of the programming types has not yet configured the

their BITX-40. That is sort of like gazing at one's navel, but it might

Hi Al, thanks for your input. It didn't transmit prior to being able
to hear myself and my 100 watt rig was set for 5 watts using an
outdoor antenna with no antenna on the Bitx. I'm going to try and
get some voltage readings tonight and log them on the chart that
someone sent me with the known good voltages. That's about all I can
do until I can get with my friend that has a scope and signal
generator.
